    <p>
    This function computes the  mean squared deviation of  the values of a
    vector or matrix <tt>
        <b> x</b>
      </tt>.</p>
    <p>
    For  a vector or a matrix  <tt>
        <b> x</b>
      </tt>, <tt>
        <b>  y=msd(x) </b>
      </tt> returns in the
    scalar <tt>
        <b> y</b>
      </tt> the mean squared deviation of all the entries of <tt>
        <b> x</b>
      </tt>.</p>
    <p>
      <tt>
        <b> y=msd(x,'r') </b>
      </tt>   (or, equivalently, <tt>
        <b>  y=msd(x,1) </b>
      </tt>)  is the
    rowwise mean squared  deviation. It returns  in each entry of the  row
    vector  <tt>
        <b> y</b>
      </tt> the  mean squared deviation  of each column of <tt>
        <b> x </b>
      </tt>.</p>
    <p>
      <tt>
        <b> y=msd(x,'c')  </b>
      </tt> (or,  equivalently,  <tt>
        <b> m=msd(x,2)  </b>
      </tt>) is the
    columnwise mean squared  deviation.  It returns in  each entry  of the
    column vector <tt>
        <b> y</b>
      </tt> the mean squared deviation of  each row of <tt>
        <b> x</b>
      </tt>.</p>
